Buck Output Ripple Management
If V
and I
increase, the output ripple associated with
the Buck Regulators also increases. The figure below shows
the safe operating area. To ensure operation in the area of
concern it is recommended that the system designer circum-
vents the output ripple issues to install schottky diodes on
the Bucks(s) that are expected to perform under these ex-
treme corner conditions.
(Schottky diodes are recommended to reduce the output
ripple, if system requirements include this shaded area of
operation. V
